The calculated line quality information is multiplexed on the transmission data of the mobile station 2 and transmitted to the base station 1. The base station 1 demodulates a received signal and extracts the line quality information, and the modulation scheme control section 11 determines whether the modulation scheme used for next transmission data is to be used, based on the line quality. Furthermore, if the remaining amount of transmission data is less than or equal to a threshold, the change of the modulation scheme is inhibited.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
